Custom Window Sizes for Older Baltimore Rowhouse Openings

If you work on enough older Baltimore rowhouses, you learn fast that window openings are seldom standard.

Why Standard Window Sizes Often Miss The Mark In Rowhouses

The choice between repair and replacement depends on the frame condition, the sash condition, and how much performance the home still needs.
